摘　　要：近年来,移动互联网技术迅猛发展,各种数据业务急剧增加,为人们的日常生活提供了无所不在的网络接入服务。由于无线传输媒介的开放性、终端的移动性、用户分布的不确定性,使得无线通信系统中数据安全传输面临着严峻的安全隐患。因此,回顾传统加密机制的不足,着重从基于信道密钥的物理层安全传输和基于信号处理的安全传输两方面进行综述,利用仿真软件,分析不同的天线配置和人工干扰对系统安全性能的影响,并在最后对物理层安全传输技术进行总结和展望。In recent years, the rapid development of mobile Internet technology and the rapid increase of various data services provide ubiquitous Internet access service for people＇s daily life. The openness of wireless media, the mobility of terminal, the uncertainty of users distribution, make the data transmission security in wireless communication system be faced with serious security risks. In review of the shortcomings of traditional encryption mechanism, two aspects of the physical-layer security transmission based on the channel key and the secure transmission based on signal processing are overviewed. In addition, the impact of different antenna configurations and artificial interferences on system secrecy performance is simulated and analyzed. Finally, the physical-layer security transfer technology is summarized and forcasted.
